2. Description of the Related Art In a conventional door, a hinge for connecting the door so that the door can be opened and closed has a first flag portion and a second flag portion constituting the hinge, both of which are formed in a flat plate shape. A hinge shaft portion fixed above and below one side end surface of the opening of the door frame and fixed to the end surface of the door by a second flag portion paired with the first flag portion, and to which these flag portions are pivoted. Were mounted so as to protrude from the space between the door frame and the door to the outer surface side thereof.

[0003]

[Problems to be Solved by the Invention] However, when the door is mounted in the conventional manner, the door frame and the hinge shaft protruding from the door are visible from the outside, so that the view as the door with the frame is poor. At the same time, it has been difficult to give the door frame and the door a flush feeling. Further, in order to prevent the door frame and the hinge shaft projecting outward from the door from being damaged by mischief from the outside, the first flag portion and the second flag portion of the hinge are respectively pivotally attached to the hinge shaft. The structure and strength of the part had to be strengthened more than necessary. Further, in the conventional hidden hinge type, it is not possible to adopt a configuration in which the hinges are connected by hanging, so that the construction on site cannot be facilitated.

[0004] The present invention has been made in view of these circumstances, to improve the appearance of the hinge frame so that the hinge shaft does not protrude outside the door frame and the door, and to give the door frame and the door a sense of flushness. The provision of a door with a frame that does not require the structure and strength of the hinge shaft to be unnecessarily reinforced, and allows the hinge to be connected by hanging, greatly facilitating construction on site. It is intended for.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described below with reference to the drawings. 1 to 4 show an embodiment of the present invention, in which a door with a frame is a door frame 1, a door 2, and a door frame 1 and a door 2.
And a hinge 3 connecting the two.

The door frame 1 has a protruding portion 1a that is substantially flush with the outer surface plate 2a of the door 2 and is formed on one of the left and right vertical frames to which the hinge 3 is attached. ing. A space 4 that opens toward the end face side of the door 2 is formed inside the protrusion 1 a in the thickness direction of the door 2. The space portion 4 is provided with a concave portion 4a along the vertical frame on the side close to the protruding portion 1a of the door frame 1 and capable of accommodating the hinge shaft 3a of the hinge 3. The door frame 1 has packing grooves 1b, 1b formed at positions facing the peripheral portion of the inner surface plate 2b of the door 2, and these packing grooves 1b, 1b are provided with the inner surface plate 2b of the door 2 and Hermetic packings 5 and 5 that keep the door 2 airtight by contact are fitted.

The hinge 3 for connecting the door 2 to the door frame 1 comprises a hinge shaft 3a, a first flag portion 3b in a flat plate shape, and a second flag portion 3c formed in a U-shape. The first flag section 3b is
An engagement hole 3d, which is fixed to the bottom wall of the space 4 formed in the door frame 1 and protrudes toward the recess 4a, is formed to be able to engage with the hinge shaft 3a.

The second flag portion 3c has a hinge shaft 3a fixed to one end formed in a U-shape so as to protrude downward, and the other end of the U-shape parallel to the first flag portion 3b. It is fixed to the end face side of the door 2 by a part. U of the second flag section 3c
The character shape is such that when the door 2 is opened, the protrusion 1a formed on the door frame 1 can enter the U-shape of the second flag portion 3c and open the door 2 by a set angle. The spacing between the characters is determined (see FIG. 2).

In the configuration of this embodiment, when the door 2 is opened, the main body of the door 2 completely comes out of the opening of the door frame 1, and only the hinge 3 is engaged with the opening of the door frame 1. It will be in the state of being combined. Therefore, even when two or more hinges 3 are attached to the door frame 1 and the door 2, the door 2 can be moved vertically with respect to the door frame 1 when the door 2 is opened. For this reason, in the field construction in which the door 2 is attached to the opening of the door frame 1, each hinge shaft 3 a fixed to the door 2 while holding the door 2 so as to be positioned outside the door frame 1 is attached to the door frame 1.

Further, since the hinges 3 housed in the door frame 1 cannot be seen from the outside, the view as a door with a frame is improved, and the door frame 1 and the door 2 are made flush with each other. Can be. Further, in a state where the door frame 1 and the door 2 are connected, the hinge shaft 3a does not protrude outward, so that the packing of the assembly of the door frame 1 and the door 2 is not damaged during transportation or stocking. Can be matched. In addition, since the hinge shaft 3a does not protrude outward and the appearance of the framed door is symmetrical, the design of the framed door can be easily changed. The hinge shaft 3a in the above embodiment is
The first flag portion 3b fixed to the door frame 1 may be projected upward and connected to the second flag portion 3c on the door 2 side.

[0015]

According to the present invention, a hinge is housed in one of the vertical frames of the door frame, and the hinge is fixed to the door frame at the first flag portion and one side of the U-shaped second flag portion. Is fixed to the door with
The U-shape of the second flag portion is such that when the door is opened, a protrusion formed so as to be substantially flush with the outer surface of the door from the door frame,
Since the interval is determined so as to enter the U-shape of the second flag portion, when the door is closed, the protrusion of the door frame does not allow the entire hinge housed in the door frame to be seen from the outside. This makes it easier to change the design by hiding the door with the frame and improving the appearance of the door with the frame.

Further, when the door is opened, the projection of the door frame enters the U-shape of the second flag of the hinge, and the door is located outside the opening of the door frame. The second flag part fixed to the door can be connected to the first flag part fixed to the door frame by hanging the second flag part fixed to the door frame by a hinge shaft protruding from the door frame. For this reason, in field construction, the door can be connected to the door frame very efficiently without using tools.

Furthermore, since the hinge shaft does not protrude outside the door frame or the door, not only is it easy to pack the framed door assembly, but also the packing of the assembly during transportation or stocking. Even in the case of overlapping, it is possible to prevent the framed door from being damaged by the hinge shaft.
